Description

Technical Field

[0001] This application relates to the field of kitchen appliance technology, and in particular to a pressure cooking appliance and its lid assembly. Background Technology

[0002] Existing pressure cookers retain high pressure after cooking, requiring depressurization before opening. To address this issue, a technology proposes a pressure cooker employing air-cooled depressurization. The pressure cooker's lid assembly includes an outer and inner lid. The outer lid comprises a main body and a decorative cover. A cooling vent in the center of the decorative cover partially exposes the inner lid. The cooker's body assembly features a rotatable cantilever with a cooling fan. When the cantilever is rotatable to a horizontal position, the fan aligns with the cooling vent on the decorative cover. A clearance between the cantilever and the cover ensures the cantilever's horizontal alignment. When the cooling fan activates, it blows hot air from the inner lid outwards through the cooling vent, rapidly cooling the inner lid and the steam inside the cooker, allowing for quick opening.

[0003] However, because there is a large cooling vent in the middle of the decorative cover, and both the decorative cover and the main cover are usually made of plastic, there are certain dimensional deviations and deformations in the plastic parts during the production process. When the decorative cover is too large and the main cover is too small, the middle area of ​​the decorative cover will arch upwards when they are assembled together. At this time, there will be a large gap between the middle area of ​​the decorative cover and the inner cover. When the user cleans, dirt will enter the inside of the lid assembly, and over time, odors will occur. Furthermore, when the middle area of ​​the decorative cover arches, it not only affects the flatness of the decorative cover, but also reduces the gap between the cantilever and the decorative cover, and may even cause the decorative cover to arch upwards along with the cantilever, thus affecting the overall appearance of the pressure cooker and the user experience. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, or at least partially solve the above-mentioned technical problems, this application provides a pressure cooking appliance and its lid assembly to solve the problems of large gaps between the central area of ​​the decorative lid and the inner lid due to deformation of the decorative lid, which affects the cleanliness of the product, and the problems of the decorative lid causing the cantilever to arch upwards due to deformation of the decorative lid, which affects the appearance of the product.

[0005] The first aspect of this application provides a lid assembly for a pressure cooking appliance, including an outer lid and an inner lid. The outer lid includes a main body lid and a decorative lid. The decorative lid is mounted on the surface of the main body lid. A cooling vent is formed in the central region of the decorative lid to expose a portion of the inner lid. A snap fastener is formed on the decorative lid, located in the peripheral region of the cooling vent and extending toward the inner lid. A mounting hole corresponding to the snap fastener is formed on the main body lid. A ferrule is provided on the inner lid. The snap fastener passes through the mounting hole and engages with the ferrule for fixation.

[0006] In some embodiments, an annular rib extending toward the inner cover is formed at the periphery of the cooling port, and an extended thin edge is formed at the end of the annular rib toward the inner cover, the extended thin edge abutting and sealing against the surface of the inner cover.

[0007] In some embodiments, the minimum horizontal distance between the latch and the periphery of the cooling vent is less than the minimum distance between the latch and the outer edge of the decorative cover.

[0008] In some embodiments, the number of the buckles is at least two, and they are spaced apart circumferentially along the decorative cover; the number of the ponytails is equal to the number of the buckles, and they are arranged in a one-to-one correspondence.

[0009] In some embodiments, the pot lid assembly includes a steam vent pipe, and the decorative cover has a mounting hole through which the steam vent pipe passes; the number of the buckles is two, and the two buckles and the mounting hole are equally spaced along the circumference of the decorative cover.

[0010] In some embodiments, the pony is disposed on the side surface of the inner cover facing the decorative cover, the middle region of the pony arches towards the decorative cover to form an arched portion, and one side edge of the arched portion forms a flange that folds towards the inner cover, and the buckle is engaged with the flange.

[0011] In some embodiments, the folded portion of the flange has a guide arc surface, and the buckle engages with the flange along the guide arc surface.

[0012] In some embodiments, the main body cover is provided with a handle, the handle having a cavity structure for hand gripping, and heat dissipation holes formed on the handle to connect the cavity structure with the outside.

[0013] In some embodiments, the handle has two opposing sidewalls and a top wall connected between the two sidewalls, the two sidewalls and the top wall together forming the cavity structure, and the heat dissipation holes are formed on both sidewalls.

[0014] A second aspect of this application provides a pressure cooking appliance, including a pot body assembly, wherein a rotatable cantilever is provided on the pot body assembly, and a cooling fan is mounted on the cantilever. The pressure cooking appliance also includes a lid assembly as described in any of the above embodiments, wherein the lid assembly is detachably mounted on the pot body assembly, and the cooling fan is used to blow air into the cooling vent of the lid assembly.

[0015] The technical solution provided in this application has at least the following advantages compared with the prior art:

[0016] 1. The pressure cooking appliance and its lid assembly provided in this application, by forming a cooling vent in the middle area of ​​the decorative lid to expose part of the inner lid, allows for rapid heat dissipation and cooling of the inner lid, achieving the purpose of quick opening; by forming a buckle on the decorative lid located on the periphery of the cooling vent and extending towards the inner lid, and forming an installation hole on the main lid for the buckle to pass through, and providing a latch on the inner lid, the buckle on the decorative lid can pass through the installation hole on the main lid and engage with the latch on the inner lid to fix it together, thereby fixing the decorative lid and the inner lid together. This design can prevent the decorative lid from warping or deforming, ensuring the flatness of the decorative lid, even if... During the manufacturing process, there are certain dimensional deviations and deformations between the decorative cover and the main cover. This results in a slight arch in the middle area of ​​the decorative cover after assembly. Due to the fixing effect between the decorative cover and the inner cover, a tensioning force is applied to the decorative cover through the inner cover. This pulls the arched part of the decorative cover back to keep it flat, thus ensuring the flatness of the decorative cover. This, in turn, ensures the consistency of the appearance of the pressure cooker and the user experience. It also prevents a large gap between the middle area of ​​the decorative cover and the surface of the inner cover from entering the inside of the lid assembly due to the upward arching of the middle area of ​​the decorative cover, which would allow dirt to enter the inside of the lid assembly. This helps to ensure the cleanliness of the lid assembly.

[0017] 2. By forming an annular rib extending towards the inner cover at the periphery of the cooling vent, and extending a thin edge at the end of the annular rib towards the inner cover, the thin edge has a thinner thickness and better deformation capacity. Thus, when the buckle of the decorative cover is engaged and fixed with the inner cover, and the periphery of the cooling vent is tightened with the inner cover, it can be ensured that the thin edge abuts and seals against the surface of the inner cover. This ensures the reliability of the seal between the annular rib and the surface of the inner cover, thereby better ensuring the cleanliness of the pot lid assembly during use and preventing gaps from forming between the two, which would allow dirt and other contaminants to enter the pot lid.

[0018] 3. By setting a folded edge on the decorative cover, a guide arc surface is formed at the folded edge, so that when the decorative cover and the inner cover are engaged, the buckle on the decorative cover can be engaged along the guide arc surface at the folded edge of the decorative cover on the inner cover, thus smoothly completing the engagement operation between the decorative cover and the inner cover.

[0019] 4. By providing a handle on the main body cover, the handle has a cavity structure for hand gripping, and heat dissipation holes are formed on the handle to connect the cavity structure with the outside. In this way, the heat dissipation holes can be used to dissipate the heat entering the cavity structure of the handle, thereby reducing the temperature rise of the handle and improving the user experience.

[0041] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0042] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0043] Reference Figures 1 to 14 As shown, some embodiments of this application provide a lid assembly 100 for a pressure cooking appliance, which can be disposed on the pot body assembly of the cooking appliance to form a cooking cavity for cooking food between the two.

[0044] Reference Figures 1 to 11 As shown, the pressure cooker lid assembly 100 includes an outer lid and an inner lid 1. The outer lid includes a main body lid 2 and a decorative lid 3. The decorative lid 3 is mounted on the surface of the main body lid 2, and a cooling vent 30 is formed in the central area of ​​the decorative lid 3 to expose a portion of the inner lid 1.

[0045] It should be noted that the outer cover is usually used as the appearance part of the pot lid assembly 100. The main body cover 2 of the outer cover can also be called the top cover, and the decorative cover 3 of the outer cover can also be called the face cover. The inner cover 1 is usually used as the pressure-bearing part of the pot lid assembly 100. It is generally made of metal. The inner cover 1 can also be called the pressure-bearing cover or the steel cover. The inner cover 1 is installed on the inside of the outer cover.

[0046] During the cooking process, the pressure cooker generates high pressure inside, which means that the pressure needs to be reduced before the lid can be opened after cooking. By forming a cooling vent 30 in the middle area of ​​the decorative lid 3 to expose part of the inner lid 1, air can be blown into the cooling vent 30 to quickly dissipate heat and cool down the inner lid 1 and the steam inside the pot, so as to achieve the purpose of opening the lid quickly.

[0047] In practice, a rotatable cantilever 4 can be installed on the pot body assembly of the pressure cooker. A cooling fan 41 is installed on the cantilever 4. When the cantilever 4 is rotated to a horizontal position, the cooling fan 41 on the cantilever 4 corresponds to the cooling port 30 on the decorative cover 3. When it is necessary to depressurize the pressure cooker, the cooling fan 41 is activated to blow air into the cooling port 30, which drives the hot air on the inner cover 1 to blow it around along the cooling port 30, thereby achieving rapid cooling of the inner cover 1 and the steam in the pot, so as to achieve the purpose of quick opening of the lid.

[0048] Reference Figures 2 to 11 As shown, a buckle 31 is formed on the decorative cover 3, which is located in the outer area of ​​the cooling port 30 and extends toward the inner cover 1. A mounting hole 21 corresponding to the buckle 31 is formed on the main cover 2. A clevis 11 is provided on the inner cover 1. The buckle 31 passes through the mounting hole 21 and is engaged and fixed with the clevis 11.

[0049] It should be noted that the "Ma Zi 11" is a component used for fixing and positioning; it can also be called a fastener or a mounting base. In practice, the Ma Zi 11 can be fixed to the inner cover 1 by welding, riveting, screw connection, or other methods.

[0050] The pressure cooker lid assembly 100 provided in this application embodiment has a buckle 31 formed on the decorative cover 3, located in the outer area of ​​the cooling port 30 and extending towards the inner cover 1. The main cover 2 has an installation through hole 21 for the buckle 31 to pass through. The inner cover 1 has a ferrule 11. The buckle 31 on the decorative cover 3 can pass through the installation through hole 21 on the main cover 2 and engage with the ferrule 11 on the inner cover 1, thereby fixing the decorative cover 3 and the inner cover 1 together. This design prevents the decorative cover 3 from warping or deforming, ensuring its flatness. Even if there are certain dimensional deviations and deformations between the decorative cover 3 and the main cover 2 during production, resulting in a slight arch in the middle area of ​​the decorative cover 3 after assembly, the decorative cover 3 can still be fixed together. The fixing action between the inner cover 1 and the decorative cover 3 allows the inner cover 1 to apply a tensioning force to the decorative cover 3. This pulls back the arched part of the decorative cover 3 to keep it flat, thus ensuring the flatness of the decorative cover 3. This, in turn, ensures the consistency of the appearance of the pressure cooker and the user experience. It also prevents the central area of ​​the decorative cover 3 from arching upward, which would reduce the gap between the cantilever 4 and the decorative cover 3, or even cause the decorative cover 3 to arch upward along with the cantilever 4, thus affecting the overall appearance of the pressure cooker and the user experience. Furthermore, it prevents the central area of ​​the decorative cover 3 from arching upward, which would create a large gap between the central area of ​​the decorative cover 3 and the surface of the inner cover 1, allowing dirt to enter the interior of the lid assembly 100. This helps to ensure the cleanliness of the lid assembly 100.

[0051] Furthermore, during the cooking process of a pressure cooker, the central area of ​​the decorative cover 3 is in direct contact with the inner cover 1, which has a higher temperature. As a result, the temperature of the central area of ​​the decorative cover 3 is higher, while the temperature of the outer edge area of ​​the decorative cover 3 is relatively lower. The temperature difference between different parts will increase the deformation of the decorative cover 3 during use. By fixing the decorative cover 3 and the inner cover 1 together, the deformation of the decorative cover 3 caused by the temperature difference between different parts can be prevented, thereby ensuring the flatness of the decorative cover 3 and thus ensuring the appearance consistency of the pressure cooker and the user experience.

[0052] In some embodiments, refer to Figures 2 to 5 As shown, an annular rib 32 extending toward the inner cover 1 is formed at the periphery of the cooling port 30. An extended thin edge 321 is formed at the end of the annular rib 32 toward the inner cover 1, and the extended thin edge 321 abuts and seals with the surface of the inner cover 1.

[0053] It should be understood that the extended thin edge 321, i.e., the relatively thin extended edge, has a thickness less than the main body of the annular rib 32. The thinner extended edge 321 has better deformation capacity. Thus, when the clip 31 of the decorative cover 3 engages with the ferrule 11 of the inner cover 1, tightening the periphery of the cooling vent 30 with the inner cover 1, it ensures a tight seal between the extended thin edge 321 and the surface of the inner cover 1. This effectively ensures the reliability of the seal between the annular rib 32 and the surface of the inner cover 1, thereby guaranteeing the cleanliness of the pot lid assembly 100 during use. It prevents gaps from forming between the end of the annular rib 32 facing the inner cover 1 and the surface of the inner cover 1, which could allow dirt and other contaminants to enter the pot lid assembly 100, causing odors and difficulty in cleaning.

[0054] In specific implementation, the extended thin edge 321 can be an annular thin edge, that is, a thin edge around the entire circle. Along the direction of the annular rib 32 toward the inner cover 1, the thickness of the extended thin edge 321 can gradually decrease, so that the longitudinal cross-section of the extended thin edge 321 forms an inverted triangular structure. This makes it easier for the end of the extended thin edge 321 toward the inner cover 1 to deform, thereby better abutting and sealing against the surface of the inner cover 1. Specifically, the annular rib 32 includes an inner sidewall and an outer sidewall. The extended thin edge 321 can be formed by extending the inner sidewall of the annular rib 32 toward the inner cover 1. In this way, dirt and other contaminants can be blocked in the inner area of ​​the extended thin edge 321, better preventing dirt and other contaminants from entering the pot lid assembly 100 through the gap between the annular rib 32 and the surface of the inner cover 1.

[0055] To improve cooling performance, the surface of the inner cover 1 corresponding to the cooling vent 30 can be recessed. That is, the surface of the inner cover 1 has a recess corresponding to the cooling vent 30. This allows the cooling fan 41 on the cantilever 4 to at least partially extend into the recess on the surface of the inner cover 1 for cooling. To ensure a tight seal between the extended thin edge 321 and the surface of the inner cover 1, an annular stepped surface 12 can be provided around the recess on the surface of the inner cover 1. The extended thin edge 321 abuts against the annular stepped surface 12 to achieve a seal.

[0056] In some embodiments, refer to Figure 3 and Figure 4 As shown, the minimum horizontal distance between the latch 31 and the periphery of the cooling vent 30 is less than the minimum distance between the latch 31 and the outer edge of the decorative cover 3. That is, along the radial direction of the decorative cover 3, the latch 31 is positioned closer to the periphery of the cooling vent 30 than the outer edge of the decorative cover 3.

[0057] With this design, the buckle 31 on the decorative cover 3 can be used to engage and fix it with the pawl 11 on the inner cover 1, thereby better forming a tension force on the cooling vent 30 area and thus better ensuring that the cooling vent 30 area of ​​the decorative cover 3 and the surface of the inner cover 1 form a seal.

[0058] In specific implementation, refer to Figure 3 As shown, multiple fasteners 34 can be provided at intervals along the circumference at the outer edge of the decorative cover 3, and the decorative cover 3 is fixed to the main cover 2 by the multiple fasteners 34 at the outer edge.

[0059] In some embodiments, refer to Figure 3 As shown, the number of clips 31 is at least two, and they are spaced apart circumferentially along the decorative cover 3; see reference. Figures 6 to 8 As shown, the number of henchmen 11 is equal to the number of buckles 31, and they are set in a one-to-one correspondence.

[0060] In practice, the number of clips 31 can be two, three, or more. In this way, at least two clips 31 are used to engage and fix the decorative cover 3 and the inner cover 1, ensuring the firmness and reliability of the fixation, and making the tension force generated between the decorative cover 3 and the inner cover 1 more uniform.

[0061] In some embodiments, refer to Figure 3 As shown, the pot lid assembly 100 includes a steam vent pipe (not shown), and a mounting hole 33 is formed on the decorative cover 3 for the steam vent pipe to pass through. The lower end of the steam vent pipe passes through the mounting hole 33 of the decorative cover 3 and through a corresponding hole on the inner cover 1, communicating with the cooking cavity. A counterweight for sealing the steam vent pipe is provided at the top of the steam vent pipe. When the counterweight is lifted, the steam in the cooking cavity is discharged through the steam vent pipe, realizing the function of steam venting and pressure reduction. The decorative cover 3 is strongly fixed to the inner cover 1 at the installation position of the steam vent pipe (i.e., at the mounting hole 33) through the steam vent pipe.

[0062] Continue to refer to Figure 3 As shown, there are two clips 31, and the two clips 31 and the mounting holes 33 are equally spaced along the circumference of the decorative cover 3. That is, along the circumference of the decorative cover 3, each clip 31 is set at approximately 120 degrees to the mounting hole 33, and the two clips 31 are set at approximately 120 degrees to each other.

[0063] Thus, the decorative cover 3 is fixed to the inner cover 1 through the mounting hole 33 and the two buckles 31, thereby evenly fixing the periphery of the cooling port 30 of the decorative cover 3 to the inner cover 1.

[0064] In some embodiments, refer to Figures 6 to 8As shown, the clevis 11 is disposed on the side surface of the inner cover 1 facing the decorative cover 3. The central area of ​​the clevis 11 arches towards the decorative cover 3 to form an arched portion 111. One side edge of the arched portion 111 forms a flange 112 that folds towards the inner cover 1. The buckle 31 is engaged with the flange 112. This arrangement is to achieve the engagement and fixation of the buckle 31 and the clevis 11.

[0065] In some embodiments, refer to Figure 7 As shown, the folded part of the flange 112 forms a guide arc surface, and the buckle 31 is engaged with the flange 112 along the guide arc surface, thus successfully completing the engagement operation between the decorative cover 3 and the inner cover 1.

[0066] In some embodiments, refer to Figure 9 As shown, the main cover 2 is provided with an installation through hole 21 corresponding to the buckle 31, so that the buckle 31 can pass through the installation through hole 21 and be engaged and fixed with the shank 11 of the inner cover 1, thereby realizing the engagement and fixation of the decorative cover 3 and the inner cover 1.

[0067] Reference Figure 10 and Figure 11 The diagram shows the structure of the decorative cover 3, the main cover 2, and the inner cover 1 after assembly. During assembly, the decorative cover 3 can be first attached to the main cover 2, and then the decorative cover 3 and the main cover 2 can be attached together to the inner cover 1. The buckle 31 on the decorative cover 3 is close to the cooling vent 30, which can tighten the annular rib 32 around the cooling vent 30 to the inner cover 1, thus preventing the decorative cover 3 from warping or deforming. The annular rib 32 has an extended thin edge 321 extending towards the inner cover 1, which can press against the inner cover 1 to prevent foreign objects from entering the pot lid assembly 100.

[0068] In some embodiments, refer to Figures 12 to 14 As shown, the main body cover 2 is provided with a handle 22, the handle 22 has a cavity structure 221 for hand gripping, and a heat dissipation hole 222 is formed on the handle 22 to connect the cavity structure 221 with the outside.

[0069] In specific implementation, since the central area of ​​the decorative cover 3 is provided with a cooling vent 30, which occupies the central area of ​​the decorative cover 3, the handle 22 is generally set at the front end of the main cover 2. The handle 22 has a cavity structure 221 for hand gripping. The cavity structure 221 has an opening for fingers to insert into, with the opening facing backward. When it is necessary to open the lid, the fingers are inserted into the cavity structure 221 to grip the handle 22, and the lid is opened by rotating the lid assembly 100.

[0070] Because the handle 22 is close to the cooling vent 30 and has a rearward-facing cavity structure 221, when the cooling fan 41 on the cantilever 4 blows air towards the cooling vent 30, the hot air blown from the cooling vent 30 accumulates inside the cavity structure 221 of the handle 22, causing the handle 22 to overheat and negatively impacting the user experience. In the above embodiment, by forming a heat dissipation hole 222 on the handle 22 connecting the cavity structure 221 to the outside, the hot air blown into the cavity structure 221 of the handle 22 can dissipate heat through the heat dissipation hole 222, thus solving the problem of excessive internal temperature rise in the handle 22 and improving the user experience.

[0071] Reference Figure 14 As shown in the diagram, the arrows indicate the direction of hot air flow. When the cooling fan 41 is working, the hot air blown out from the cooling port 30 flows in the direction of the arrows into the cavity structure 221 of the handle 22, and then flows out through the heat dissipation holes 222 on the handle 22, thereby reducing the internal temperature rise of the handle 22.

[0072] In some embodiments, refer to Figure 12 and Figure 13 As shown, the handle 22 has two oppositely arranged side walls and a top wall connected between the two side walls. The two side walls and the top wall together form a cavity structure 221, and heat dissipation holes 222 are formed on both side walls.

[0073] This design allows the hot air flowing into the cavity structure 221 of the handle 22 to flow out in different directions through the heat dissipation holes 222 at different locations, thereby increasing the speed of hot air flow and improving the heat dissipation effect.

[0074] Other embodiments of this application provide a pressure cooking appliance, including a pot body assembly, a rotatable cantilever 4 on the pot body assembly, a cooling fan 41 mounted on the cantilever 4, and the pressure cooking appliance also includes a lid assembly 100 as described in any of the above embodiments, the lid assembly 100 being detachably mounted on the pot body assembly, and the cooling fan 41 being used to blow air into the cooling vent 30 of the lid assembly 100.
